45th Binghamton Geomorphology Symposium Report

Ted Stryk • September 23, 2014

The 45th Binghamton Geomorphology Symposium, usually focused on terrestrial studies, shifted this year to planetary science. Ted Stryk gives us an overview.

Cassini's awesomeness fully funded through mission's dramatic end in 2017

Emily Lakdawalla • September 03, 2014

Last year, rumors swirled that NASA may be so pinched for dollars that the agency might end the Cassini mission early. Today, Cassini received the welcome news that it has formally been funded through the planned end of its extended-extended mission in 2017. A huge congratulations to the Cassini mission!

On the masses and motions of mini-moons: Pandora's not a "shepherd," but Prometheus still is

Emily Lakdawalla • July 04, 2014

As Cassini celebrates 10 years at Saturn, we're beginning to see its long-term observations of Saturnian moons bear fruit. A surprising new result: While Prometheus exerts control over the F ring and Atlas, Pandora -- long thought to be a shepherd of the F ring -- does not.

A close look at Saturn's closest moons

Emily Lakdawalla • June 26, 2014

A new composite image of the eight named moons that orbit closest to Saturn, and a list of all the best Cassini observations of these moons.

Of Rings and Resolution

Bill Dunford • June 23, 2014

Seeing Saturn before and after Cassini.

Intro Astronomy 2014. Class 8: Icy Galilean Satellites, Saturn System

Bruce Betts • April 11, 2014

Explore the icy moons of the Jupiter System and tour the Saturnian system in this video of class 8 of Bruce Betts' Introduction to Planetary Science and Astronomy class.

LPSC 2014: Titan's Land of Lakes

Emily Lakdawalla • March 31, 2014

Report from a varied session on Titan's lakes at this year's Lunar and Planetary Science Conference.

Snapshots of Science from the 2014 Lunar and Planetary Science Conference

Emily Lakdawalla • March 25, 2014

Vignettes from dozens of LPSC talks: GRAIL and LADEE at the Moon; ice and craters and conglomerates and organics and gullies on Mars; polar deposits and volatile elements on Mercury; tectonics on Enceladus; and more, until my brain was so full I could barely speak.

Cassini images in motion.

Titan's lakes: The basics

Emily Lakdawalla • March 15, 2014

Since Seth MacFarlane tweeted that this weekend's episode of Cosmos was going to include a segment on lakes on Titan, I thought I'd write a post explaining the basics of Titan lakes.

The Two Faces of Phoebe

Daniel Macháček • February 13, 2014

Cassini flew past Phoebe on June 11, 2004, on its way to entering Saturn orbit. The flyby was almost perfect but overexposure of some images have prevented color mosaics from being produced. Even though Phoebe's body is gray and dull in color, the absence of color images always provoked me. By using VIMS data, I have now produced color mosaics.

Intro Astronomy Class 1: Tour of the Solar System

Take a tour of the Solar System in the video of class 1 of Bruce Betts' Introduction to Planetary Science and Astronomy class.

Enceladus huffs and puffs: plumes vary with orbital longitude

Emily Lakdawalla • December 11, 2013

In which I finally get around to writing about a paper published last August: Enceladus' plumes sometimes spout more and sometimes spout less, depending on where Enceladus is in its orbit. This discovery was enabled by Cassini's longevity at Saturn, and we'll be able to follow up on it, as long as Cassini is allowed to complete its mission.

Pretty picture: newly processed high-res view of a fractured icy moon, Dione

Emily Lakdawalla • December 04, 2013

Here's a lovely new view of Dione, one of the lovely mid-sized icy moons of Saturn, assembled by Daniel Macháček.

Just what is going on in that magnificent Cassini image of Saturn?

Emily Lakdawalla • November 13, 2013

It took months of work (and no wonder) but the wait was worth it: here is Cassini's spectacular view of Saturn, captured on July 19, 2013, as Cassini passed through Saturn's shadow. If you're a little confused by the image, I'm here to help: I've posted a video explainer.

DPS 2013: The fascination of tiny worlds

Emily Lakdawalla • October 17, 2013

In which I summarize Joe Veverka's Kuiper Prize talk at the Division for Planetary Sciences meeting: "Small is NOT Dull: Unravelling the Complexity of Surface Processes on Asteroids, Comets and Small Satellites."

America's Pastime: Planetary Science

Mat Kaplan • October 15, 2013

Apologies to baseball fans and others for the theme of this week's Planetary Radio preview, which has star player Emily Lakdawalla on deck.

Europe Will Select Its Next Major Science Mission in November

Van Kane • September 25, 2013

The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.

Probing Titan's Atmosphere

Sarah Hörst • August 26, 2013

By now I hope that everyone has seen some of the spectacular images of the Saturn system (and especially Titan!) from the Cassini-Huygens mission. However, the measurements that often make my heart race are taken by instruments that reveal Titan in ways that our eyes cannot see.

Pretty picture: spectacular Saturn and Titan

Emily Lakdawalla • August 15, 2013

A lovely view of the ringed planet and its hazy moon seen from nearly behind them just a few days ago.
